Question for microwavesvc and others: I have a ge jw740 microwave with a push button door opener. By accident, I noticed that if I push the button halfway (before the door actually swings open), the microwave light, fan, and turntable come on suddenly. I can't tell if the microwave is actually heating, or if it's just the light, turntable, and fan that are working. I don't exactly understand the physical relationship between the door switch and the door latches, but why would this happen? As I depress the button to open the door, shouldn't all functions except for the interior light be automatically shut down? I'm just trying to find out of this is normal or not, or whether there is some malfunction that I should be concerned about (I don't want the microwave accidentally turning on in the future as the door is completely opened). Thanks in advance.
What's happening is you are activating one door switch a little before the other, and that is causing your light, fan, and turntable to come on. The plastic parts are not perfectly rigid, so they flex a little when you press the button, and that causes the lag to be more apparent. Even if you press the door open faster and look really close, you may notice the light, fan, and turntable coming on for a split second. That's perfectly normal. The relay on the control board must also be turned on before it will actually be cooking.
The latter. You're not going to activate the relay by way of the door.

Door catches.
One of the latches may be bent/misaligned
and is not lifting the other latch clear of the housing. Remove from
any power source, remove the cover of the cabinet. Slacken off the
clamp mechanism and ease the clamp over the guide to allow the door
to open. When a new door lever is in place, the door may be easily
adjusted by slackening off the screws that clamp the door
catch/actuators in place whilst holding the door closed and then
tightening the screws. The rear of the door may be adjusted by
slackening the lower door hinge screws and adjusting as required.
I
hope that helps.

Thanks for your answer.
One last question--you mentioned that the relay must be turned on for the microwave to heat. Is there any way the relay/control board can accidentally be activated by what I did (partially depressing the door button for a few seconds), or do you need to physically set the timer and push the start button to turn on the relay/begin heating?
Thanks again for your help, it's much appreciated.
Door on Advantium microwave, difficult to open. I wonder if this has something to do with handles being broken? Can I use liquid wrench to lubricate the latching mechanism? There should probably be a release button, maybe in the next design.
Intermitently turns on, the fan and light turns on when the door is opened, but the turntable does not move. Seems to work fine and this only happens occasionly. Could this be the switches?
if door is open the microwave is normal. Shut the door and the fans turn on and won't shut off until door is opened
Fan stays on when you open door after you heat something
